When it's more than just a regular love, When you love a person enough to cut someone open and drip candlewax into their wound all for the person you love.

Person 1: I love you.
Person 2: I love you harder.
Asshole : Haha, Person 1's a bitch.
Person 2: *grabs Asshole and throws him to the ground. He then pulls out a razor blade. Person 2 cuts that presons arm open. He then pulls out a candle and a lighter. He drips candle wax into the guys wond. Then walks away*
